Added full support for easing in all shorthand effects methods (hide, show, toggle, fadeTo, slideUp, etc.). Previously, these methods could only be used with two of the three (speed, easing, callback) arguments, or, in the case of fadeTo, 3 of the 4 (speed, opacity, easing, callback) arguments. Added three more sets of tests to the series of "Chain" tests. Fixes #7014
